egg lawsuit

Thirteen states filed a lawsuit Monday with the U.S. Supreme Court challenging a California law that requires farmers to give egg-laying hens more space.

The lawsuit, filed by Missouri Attorney General Josh Hawley, claims the 2015 California egg law is a violation of two federal laws. One prohibits state laws from discriminating against citizens of other states and another bans one state from imposing its farming regulations on other states.
